FLOOR PACKING FOR MOVABLE CLOSURES OF ALL KINDS FOR USE IN WATER.

Application filed December 18, 1922. Serial No. 607,465.

To all whom it may concern:

Be it known that I, Tnnonon Bnormn, residing at Gustavsburg, Germany, have invented certain new and useful Improvements in a Floor Packing for Movable Closures of All Kinds for Use in Water, of.

which the following is a specification.

This invention relates to a floor packing for movable closures of all kinds for use in water, as for instance sluices, sector-shaped closures, segment-shaped ones, and the like, and consists in the feature that a packing beam is attached to the respective closing member by means of an elastically movable plate in such a manner that it is capable of elastically yielding in a direction practically contrary to the direction of the pressure of the Water, the arrangement beingsuch that said beam is pressed by this pressure towards the place to be tightened.

The invention is suited chiefly for immersible closing members, and offersespecially in connection with the closing rollers of roller weirs the possibility of constructing these rollers in such a manner that the objections raised in many an instance against roller weirs maybe dropped.

Packing ledges attached to elastic sheetmetal plates have already been employed in connection with weirs, it is true, but neither have they been used hitherto as packing members for channel floors in the manner forming the subject-matter of this invention, nor have they been connected with a roller weir in the manner described hereinafter and shown by way of example in the accompanying drawings, in which Figure 1 is a transverse section, in'diagrammatical representation, through the chief members of the arrangement and combination of parts forming in its entirety a roller weir with the packing combined therewith, and Figure 2 is a transverse section, on an enlarged scale of the roller weir and the packing is attached. I

The packing consists of a packing ledge 0, Fig. 2, and of an elastic sheet-metal plate 7?, to the upper rim of which said ledge 15 affixed. The plate p is at its inner surface subjected to the pressure of the head water and is acted on by it practically in the direction from the tail water to the head water so that the packing ledge is pressed against the floor-portion d located between the head water and the tail water. In the form of construction shown as an example the elastic sheet-metal plate ;0 forms a movable wall of a box is having oppositely to p a rigid wall m. The movable wall which extends upwards from the bottom of that box does not extend to the top of it but a slot to is left through which the water may enter into the box in, or may keep it filled respectively. The water in the box transmits the pressure'of the head water to the movable wall 1), or to the elastic sheet-metal plate p respectively, whereby the packing ledge 0 is pressed against the floor portion d, as already mentioned.

To obviate unduly strong bending of the plate p bolts 1' are secured to the ledge 0 and extend through holes of the wall m behind which the heads of the bolts serve as stops and the wall m serves as an abutment for these stops.

In order to keep the box filled even if the slot w should have been obstructed by mud or foreign bodies carried along by the water, pipes s establishing a direct communication between the head water and the box may be provided. The'entrance openings of these pipes lie between the upper water level and the floor, that is to say, in the clean water, viz. below foreign bodies floating in the water.

The tubes .5- may be employed also for clearing the box is, provided, the sides of this latter be slidable in guides, or form slides respectively.

The weir, in the example illustrated in Figures 1 and 2, is a roller weir, of which a is the roller, to which is secured a (preferably curved or bulged, viz. in the direction to the head water) strong plate g, to the free rim of which are affixed the parts forming the box is. This is a particularly advantageous combination of a roller Weir with the packing device described. The arrangement of the plate Q at the roller (1 is such that when this latter is in its normal closing position (as shown in full lines in Figure 1, in which the upper dotted circle indicates the uppermost position of the roller a, and the lower dotted circle'indicates the lowermost position of the same) the box 70 lies-adjacent to a step I), or to the side of an appropriately large transverse groove or cavity, provided in the floor, the packing ledge being then in close proximity to the place d, or practically in contact with it, especially under the pressure of the head water, as already described. At any rate, there remains no unduly wide passage between the ledge o and the place d, and-this is the casewhen the roller a is in its lowermost position. This effect is due partly to the shape of the plate 9, partly to the shape of stationary oblique racks c affixed to the side walls :0 of the plant and co-operating with 'cogged rims g of the roller and being bent off at their lower ends, at 6, Figure 1, into vertical direction, the relative position of the parts concerned being such that there is hardly any gap between the plate 9 and the place (1 of the step or transverse groove or cavity of the floor.

h is a chain or the like afiixed at its lower lines in the top of Figure 1.

Iclaim: 1. The combination, with a movable 'clos ing member for use in water, of an elastic late attached to said member, a packing edge secured to said plate, and means whereby the latter is subjected to the pressure of the water, in a direction contrary to the direction of the pressure of the same when said closing member is in its working position and said ledge is pressed into sealing position, as set forth.

2. The combination, with a movable closing member for use in water, and with a plate-shaped extension projecting from its closing side, of an elastic plate attached to extension, a packing ledge secured to said plate, subjected to the pressure of the water,- in a direction contrary to the direction of the pressure of the same when said closing member is in its working po- SItlOI), and said ledge is pressed into sealing position, as set forth.

3. The combination, with the roller of a roller weir, and with a plate-shaped extension projecting from the closing side of said roller, of an elastic plate attached to said extension, a packing ledge secured to said plate, and means whereby the latter is subjected to vthe pressure of the water, in a direction contrary to the direction of the pressure of the same when said roller is 1n its working position and said ledge is then pressed into sealing position, as set forth.

4. The combination, with the roller of a 'roller weir for damming a channel, and

water, of an elastic plate attached to said extension, a packing ledge secured to said plate, and means whereby the latter is subjected to the pressure of the water and said ledge is pressed into sealing position said channel being provided with a cavity located below the weir and adapted to receive said elastic plate with its ledge, as set forth.
